A quality improvement intervention on surgical prophylaxis impact in antibiotic consumption and cost in selected surgical procedures.

[BACKGROUND] Improper compliance with antibiotic prophylaxis (AP) in surgery is associated with an increased risk of surgical site infection (SSI), and impacts the efficiency of healthcare.

[OBJECTIVE] Evaluate the impact of an intervention in compliance with AP in selected surgical procedures and its effect on antibiotic consumption and cost.

[METHODS] A prospective interventional study was performed in a community hospital from January to December 2022. The baseline period was considered January-April 2022 and the intervention period May-December 2022. All patients who underwent cesarean section, appendectomies, hernia surgery, open reduction and internal fixation (ORIF), abdominoplasty, and cholecystectomy during the study period were selected. The intervention includes staff education, pharmacy interventions, monitoring the quality of prescriptions and feedback, and improved role of anesthesia staff, and department champions.

[RESULTS] The study involved 192 and 617 surgical procedures in the baseline and intervention periods respectively. The compliance with timing, selection, dose, and discontinuation achieved 100%, 99.2%, and 97.6% from baseline figures of 92.7%, 95.8%, and 81.3%, respectively. The antibiotic consumption was reduced by 55.1% during the intervention with a higher contribution of other antibiotics (94.1% reduction) in comparison with antibiotics as per policy (31.2% reduction). The cost was reduced by 47.2% (antibiotic as per policy 31.9%, other antibiotics 94.2%).

[CONCLUSION] The implemented strategy was effective in improving the quality of antibiotic prophylaxis with a significant impact in reducing antibiotic consumption and cost.
